iStockphoto/Thinkstock(NEW YORK) -- Dementia, the severe decline in mental abilities, such as memory and reasoning, affects four to five million people in the United States, most of whom are elderly. A study in the journal Neurology finds that keeping the mind active, specifically by reading and writing, can help prevent mental deterioration.

Researchers studied 294 elderly people for six years before their deaths at an average age of 89 and found that those who took part in "mentally stimulating activities" -- like reading and writing -- over the course of their lives had a slower rate of mental decline as compared to those who hadn't.

In fact, those subjects who frequently took part in mental activity late in their lives decreased the decline of their mental faculties by about 32 percent.

Researchers believe that it is important to begin partaking in mental activity during childhood and to maintain it well into your later years.

The first time she took her driving test, tears welled up in her eyes and she could not see the road. She pulled over mid-test, stopped the car, and told the tester, "I just can't do this."

"Even though I was prepared for it, leading up to it I was really sweaty," said Sultana. "I started to feel nervous, and during the test I started crying."

The second and third time she took the test, Sultana could feel her stress level building. Again, she choked.

"I just couldn't concentrate," she said. "It became such a long process to pass this test."

Sultana was wrapping up her final college year before she got the nerve to try it again. This time she brought a friend along. Right before the test, her friend assured her there was nothing to worry about.

Sultana thought about failure, she told her friend. She thought about what her tester thought about her. She thought taking a deep breath to quell the anxiety won't work for her. But she also thought, "I've got to pass this thing." She didn't want to take this test again.

"Telling someone put things in perspective for me, that it's just a test that I've been prepared for," said Sultana, who went on to pass the test.

Letting out all of her fearful thoughts before test time may have done the trick, according to a new study published Thursday in the journal Science. The study suggests that simply writing about your anxiety just a few minutes before a high-stakes event can help you perform significantly better.

Researchers conducted four separate studies that focused on test-taking anxieties of high school and college students. Before giving the students a test, researchers assigned different groups of students with high performance anxiety to either write down their anxieties about taking the upcoming test, write freely about any topic, or not write at all.

"I am afraid I am going to make a mistake," wrote one student in the expressive writing group.

"I just want to stop thinking about how I am going to fail," another student wrote.

The study found that those who wrote about their test anxiety in some cases received a whole grade letter higher than those who wrote about an unrelated event, or did not take the time to write.

"It's really a counterintuitive finding -- that dwelling on your worries can have a positive impact," said Sian Beilock, an associate professor in the department of psychology in The University of Chicago and co-author of the study.﻿
